Cubieboard Cluster Ceph Test

Trying to setup a big data backend for collection data from the web. Setting up hadoop or other distributed filesystem is the first step. Here is my founding for Cubieboard.

First we show our physical harddrive write speed in Cubieboard1 with a TOSHIBA HDD 1TSince this time I'm testing the io speend for overall performance I use no cache ( I normally benchmark real use case in desktop without) oflag=direct

Note: You may not able to find 2T 2.5" HDD directly or more expensive then a Portable USB3.0 HDD. What I do is find the easiest possible disassemble it. So I pick the cheapest ADATA 2T HDD just about 100$ USD

The follow benchmark run about 5 times each over 5 different nodes. As show you below, 2T is about 20% slower then 1T model.

You may also notice the first run always the slowest is possible the spin up time for the first run compare to the rest. Since no cache and other configuration in the physical write cubieboard2 has no benefit compare to cubieboard1. And the raw hard drive basically speak for itself.
